Re: [Discuss-gnuradio] Confirming uhd.set_command_time is working

2015-04-29 Thread Anderson, Douglas J.
Thanks Marcus, that's what I assumed (that the code that spits back the Successfully tuned bit and stores the current freq settings) is independent of the queue that holds the timed commands. I'm wondering if there's no other way to verify that the timed command is actually being delayed.

John, Thanks for replying. The question is, how do I do this? We both agree the zeros need to go. What I'm not sure on is how to do that. I'd rather keep this contained to GRC, because I don't like maintaining python files not connected to grc. Can you explain how you do this or provide an

Thanks for helping me through this Marcus, I appreciate it. Another words, if I installed Doxygen on my non-air gapped computer and used this to make the target.tar.gz then the air gapped computer must have Doxygen installed as well for the install to work? I'm running into a problem that might

I originally installed GNU Radio on this computer when it was networked via pybombs. Since then, the computer has become air gapped (no internet connection allowed). I need to update the install to the latest versions of UHD and GNU Radio. Two questions: 1) Is there a way that would allow me to

Marcus, I'll try the second approach. I created the target.tar.gz from a computer (same OS) that is networked and fully updated. I have copied this over to the air gapped machine, but now what do I do? Just having the target folder isn't enough to update the install. How do I update from here?

Well, if you installed into a prefix on the air gapped computer, too, you'd just overwrite everything in there with the contents of the archive. You must make absolutely sure that you bring all distro packages that are related in *any* way to the software you'll run to the same version that you've

Hi Richard, 1) depends. Many of the things that pybombs does actually consist of calling your distro's package manager. So if you can do that with a DVD source, you're set (I remember this being relatively easy on debian, with a DVD actually being a remote just like debian's repo servers are);

Richard, no solution here, but this is interesting because these kinds of problems are one of the reasons why we're re-working PyBOMBS. Are USB drives allowed? I guess if so, you could fetch-all on one machine, update a USB drive, and then have PyBOMBS read repos from that. Of course,

Hi Martin, Yes you're right that we can't use USB drives, but I should be able to do the same thing on a DVD. Can you explain the steps you would use to create the USB drive and I will do that on a DVD instead. This is the part I'm just not sure how to do. v/r, Rich On Wed, Apr 29, 2015 at

Hi, I am having a failure with the attached GRC flowgraph. It is a four channel Tx/Rx loopback using 2 Ettus X310 USRPs. The flowgraph is simple in that the Tx is simply a constant (center freq tone) and the Rx is displayed on a QT freq sink. Externally, the RF signals are looped back from TX to
